Leonid Meteor Shower Tonight 155

Posted by jamie from the keep-looking-up(tm) dept.
The annual Leonid meteor shower hits tonight, as the Earth moves through the orbital path of a comet. The show is exceptionally good every 33 years, and in 1966 it was so dramatic some people thought the world was coming to an end. No one knows how it will look this year, so keep your fingers crossed. You don't need a telescope, just warm clothes, patience, and clear skies. The Leonids' unpredictability make it worth going out as soon as it's dark, but the peak is supposed to be between 11 PM and 1 AM (EST?). If it's cloudy, check out NASA's weather-balloon webcam.

    Here [amsmeteors.org] is some great info about the Leonids that I've found from the American Meteor Society [amsmeteors.org]. The site also has info on all the other metoric events throughout the year.

  • I've honestly never seen a meteor shower. I definitally hope to see one. Once, my super-geek and super boring science teacher tried to get my 8th grade science class watch a meteor shower, but there were like 2 people out of 91 that showed up!!
  • NPR ran a spot on the meteor shower this morning. One thing they mentioned is that hard-core astronomers are heading to Europe and the Middle East because that is where the center of the storm will be at peak intensity. They said that best viewing will be between 9-10pm EST, and the possiblity exists for up to 1000 shooting stars per hour. The main subject was how vulerable the sattelites in orbit are going to be. Tune in your favorite NPR station today at 4pm, they should rerun the spot.
  • In (I believe, I may be off by a year or two) 1833, Abraham Licoln was awakened during the wee hours to be told that the final judgement had arrived. Apparently, God was pretty pissed. The Leonids were putting on one of the best shows in (Western) recorded history, and they had no idea how to deal with it.
  • First, on the astronomy side, this will be the last good Leonid meteor shower. Ever. The Earth will move out of the path of the cometary debris, from now on, which will result in steadily weaker showers, eventually fading out to nothing.

    Second, this will STILL not be multicast! Even NASA, who have multicast facilities, won't interrupt some pre-recorded multicast which they've been repeating every 10 minutes since mid-day, for the meteor shower of the millenium. Last year, all of the sites broadcating webcams and RealAudio links were overloaded to the point of collapsing. BUT THEY WILL NOT LEARN!!! What is WRONG with these people?!?!?! The meteors should land on these idiot's thick skulls and thwack some sense into them!

    (Can you tell I like multicast technology, and DON'T like horrible lag?)

  • You won't see much until the radiant (in leo) rises, which will be about 2230 local time (depending a bit on your latitude, like sunrise).

    And don't trust the predicted peak time too much. Last year it was about 18 hours earlier than predicted. We had an excellent display in Scotland.

  • I used SkyMap to check the position of Leo tonight, and it shows that that constellation will be below the horizon tonight on the US eastern seaboard. I think our European geek brethren may be able to see it, though?
  • Yes they will get the full force of the show. It will be highly visible in the US after 3am when the Moon sets.
  • From what I heard, some locals in the Midwest (US) called up the police and reported "planes on fire" last night. At U.S. Fighter pilots said that they were privvy to some great fireworks from the shower. And, since it's not in the FAQ: How do you post a new message (new thread)?
  • I saw one of them on my way home from work last nite (7pm, Columbus, Ohio). It streaked across the sky, and eventually brokeup into smaller pieces that each streaked and then faded into nothingness. (and yes I was cursing that I didn't have my Oly2000 digital camera with me at the time) I've watched meteor showers before, but I never saw one this big, bright, or with such a long tail.
  • Anyone going to be on 2m or 70cm tonight??? I know I will :)

  • reply to the original post, not to users' comments. (same line as "threshold," "change," you'll find "reply")
  • Because we had neglected a small part of the physics - the meteor stream is in resonance with Jupiter.

    This year we think we've got it figured - everyone in europe should be in for a good show.
  • I was out driving in Detroit, MI and I think I saw the same one! It looked like a gigantic sparkler trail in the sky, moving WSW -> ENE, slowly breaking up into smaller trails.

  • Peak rate 2am /UTC/ (~not~ EST) (Score:5)

    by Cally ( 10873 ) on Wednesday November 17, 1999 @06:11AM (#1525416) Homepage
    Times for astronomical events are given in UTC which is the same as GMT. The expected peak Zenithal Hourly Rate (ZHR) of 15,000 has been predicted for 2am GMT.;

    Note that the ZHR is a /theoretical/ maximum that would be seen by an observer if the radiant (the line of comet's orbit, ie the place in the sky where the meteors appear to radiate away from) were directly overhead. Actual observed rates are always lower.

    Hints and tips for observing :

    • No smoking ! It ruins night vision.
    • Get as far away from light pollution as possible.
    • The radiant rises at about midnight local time in the northern hemisphere, in the east (of course ;) )
    • Use a deckchair or lawn chair to prevent a permanent crick in the neck.
    • wrap up WARMLY -- good skies == clear skies == very cold !
    • Hot drinks (counter-intuitively) do NOT warm you up if you're outdoors.
    • If your location is clouded in, set an alarm clock for 60-90 mins and check again. If they storm, and you miss them, you'll kick yourself !

    Finally, don't be too disappointed if you "only" get a ZHR of a few hundred. Last year's observations allowed significantly better understanding of the separate streams of debris coming off the parent comet. Predictions are for a relatively quiet year next year, but much higher ZHRs in 2001 and 2002.

    Clear skies, all !

    1999 Leonids: Rapid Information Dissemination
    =============================================

    Dear meteor observer,

    >From earlier communications, you have learned that the IMO is setting
    up a communication network to obtain reliable information as soon as
    possible after the event in the morning of November 18. We invite you
    to contribute to this effort.

    First of all, we want to point out you must DISTINGUISH between the
    USUAL OBSERVATIONAL REPORTS, such as collected by the IMO's Visual
    Commission, and which may be used for detailed, global analyses, and
    the "EXPRESS REPORT" described below which serves as sole purpose the
    compilation of a rough but reliable picture of the activity within
    hours after the event.

    The EXPRESS REPORT should have the following format:

    Meteo R. Observer
    Fireball City (45N 10E)

    Time Interval (UT) Lim. Magn. Nr. of Leonids Remarks (if any)
    ------------------------------------------------ -----------------------
    01:15-01:30 5.8 27 None
    01:30-01:45 5.9 56 None
    01:45-02:00 6.1 156 None
    .
    .
    .

    To the extent possible, bin your observations for this "express report"
    in time interval of 15 MINUTES.

    (Again, the full report of your observations will be different from
    this express report, as shorter intervals are required as well as
    magnitude distributions and some additional data - see the earlier
    posted article with visual observing hints - but the above data
    suffice for the purpose indicated.)

    If you wish to collaborate with the IMO in this respect, please send
    your express report for the night of November 17/18 ONLY (or, of course,
    for any unexpected activity you might happen to witness)
    *** IMMEDIATELY AFTER THE OBSERVATION *** to the following email
    addresses:

    wgn@imo.net
    gyssens@hcoss.uia.ac.be

    The latter is a back-up address in case Web-site access to www.imo.net
    would prove to slow down our computer too much. This back-up address
    will be active only on November 17 and 18!

    Thank you in advance for any collaboration we may receive!

  • I don't believe it's the last good shower EVER. I've read it will be the last for about 100 years or so, because the comet's orbit will be altered somewhat when it passes near Jupiter. Astronomers believe, however, the the orbit will "somehow" return to it's previous path after about 100 years, and then our great-great-grandchildren will get some great shows again.
  • It SHOULD be visible from Europe...

    But!

    Looking at the current infrared satellite images (http://www.nottingham.ac.uk/pub/s at-images/D2.JPG [nottingham.ac.uk]) it's not looking good...

    The sky is way too cloudy... too bad ;(

    Maybe England, Spain or France has some chance.
  • I live just outside Chicago and the lights are not very bright. Last night, (6:15pm) I saw what I thought (at the time) was a very large green and gold firework flying across (from west to east). It was very large and lasted for about 20-30 seconds. I didn't realize that it was a piece of a comet until I heard reports on the radio that people from Central Illinois to Wisconsin had seen the same thing. Did anyone else it? Any ideas on the size of it?
  • It was almost certainly a piece of space junk.

    I doubted it too (when I got home my stepson swore it was a UFO, heh), but this morning on the way in all the radio stations were talking about it, mentioning it was verified from Wright Patterson Airforce base in Dayton, OH. which is just west of Columbus.
    Just now I checked the website for the local newspaper and found an article here [dispatch.com] (note the logic of columbus residents calling the police) that has quotes from some OSU [osu.edu] Astronomers verifying what you said - that it was junk and not part of the Leonids.
    Damn! It certainly was brilliant looking. I've got my hopes up for tonite now!!

  • Hate to rain on your parade, but ...

    First of all, that probably was a satellite (possibly an Iridium). 20-30 seconds is a long time for a meteor. Secondly, if it was a meteor, it was probably a sporadic and not associated with the Leonids since Leo doesn't rise until about 1am. Thirdly, it was moving in the wrong direction to be a Leonid.

    Last night at around 6PM CST, there was this huge fireball seen heading East from Chicago, Illinois (where i live) and was seen in Wisconsin all the way out to Ohio. This was most likely part of the meteor shower but I don't know if anything that impressive will be seen tonight. The only reason I know it wasn't a UFO is because they have an offical report [spacescience.com]

    I basically was getting out of work, looked up and saw this huge greenish fireball. it then seemed to split into 3 parts leaving a long trail behind it and was heading towards lake michigan. It took around 30 seconds to pass over me and out of sight. I was like 'whoa' and then heard people on a local radio station getting calls about it. It was really cool.

    Good news is that I think I could live with that image as my memory of the meteor shower, so that means I can actually get some sleep tonight!

  • If the meteor was rather large and skipping on the surface of the ion sphere, it's quite possible. I saw this phenomenon as well. And it was coming from the southeast, the direction of the Leo constelation. It just continued to head past everyone towards the northwest. And yes, it most likely was an unusual chunk of rock, with a reference here [spacescience.com] reporting it as part of the shower.

    Basically, the way the world was turned, the only debris that the midwest would see would be rocks that only skipped on the surface, due to the steep angle due to the early time. At 1 AM, we might see some short streaks due to meteors coming straight down, burning out quickly. but in this particular case, we got to see a very large one burn out slowly no the upper levels of the atomosphere, and it was quite impressive!

    The "standard" mbone tools (SDR, VIC and RAT) have become very usable, even for "Joe Average". There is an "integrated" environment, supplied by the University College of London (UCL), called "Relate", which merges everything together into a very simple, easy-to-use desktop.

    No, and you shouldn't either. This particular meteor storm has recurred every year, with peaks every 33 years. The last peak was 1966, and was by all accounts spectactular.

    If you're worried about the conjunction of this with the turn of the millenium, you should relax on this as well. The christian counting of years was calculated by Dennis the Short, in the mid 500s at the direction of the Pope. He worked off of events of the time that modern bible scholars and historians now know were inaccurate. The best calculations show that the birth of Jesus was 4 years earlier than Dennis calculated. Thus, the millenium really turned in 1996. You missed it.

  • Took the trash out and looked up and there was a fireball that was just a bit dimmer than the moon. It was in the North sky and its tail stretched longer than my house is wide - in my field of view, that is. It was very blazing and lasted a long time. Neatest celestial event I've seen since those impacts with Jupiter (? I think) a few years back. COOOL!
  • In short, NO. The effect lenoids can have on satellites can be equated to shooting it with a .22.

Imagine a static charge building up on your PC case...ZAP*!*!
  • Your local time doesn't matter if the cloud of dust is not there at the same time. Just before dawn is the general rule.

    The "Peak Time" being mentioned is when the comet's orbit intersects that of the Earth. From experience we know that the dust cloud is not always present at that point. The 33-year cycle is from several past observations -- the math is still being worked on.

    As was already mentioned, the dust cloud was 12-18 hours off of last year's orbital intersection. Plus or minus 12 covers a 24-hour period. Youse watches the skies, youse takes youse chances.

    "On Tuesday evening, locally Nov. 16, at approximately 7:07 EST / 6:07 CST (November 17, 1999, 0007 UTC), a brilliant fireball lit up the American midwest, travelling slowly from west to east, and apparently breaking apart in transit. The AMS has received reports about this event from locations across central North America, from southern Canada to northern Texas (!). Regardless of what is being reported at other web sites and in the popular press, this event could NOT have ben associated with the Leonid meteor shower. At the time of this event, North America was completely in the shadow of the Leonid stream, with the radiant located slightly east of the anti-zenith, that is, underfoot. This object is most likely a very bright sporadic fireball (of which there are a few each year of this magnitude), or perhaps reentering space debris. "

By now it is too late to even care because our demise would be inevitable.
  • This is a serious issue. The Space Telescope Science Institute has taken steps in the past [stsci.edu] to minimize the chance of Leonid damage to HST, orienting the aperture away from the Leonid direction. There were plans to do the same thing this year, but with the telescope in safe mode it is not possible to do the protective move. While the chances HST will be damaged are still very small, the potential loss if very high, so every bit of protection counts!
  • Sorry about that, wrong story (just goes to show you having too many windows open at once can be a probem...).
  • Yeah, whatever it was -- space junk (Mir?), a meteor, an asteroid -- it was very cool looking. I wish I'd had a camera with me, not that it would probably have gotten a very good picture.

  • There are several reports on sci.astro.amateur about a large bolide in the midwest travelling NW->NE and being visible for 10-15 (some said 20) seconds. It was apparently an Earth-grazer, which accounts for its long duration. Whether it was a Leonid is in question (one observer puts the origin in Serpens Caput), but who cares - sounds spectacular from all accounts. I'm jealous.

  • Woo, a spelling flame. Finally, I get to plug this little-known fact:

  • This works in many areas, but not in NYC, where law-abiding citizens are not allowed to defend themselves.
  • Wouldn't they have moved it before putting it in safe mode, knowing that the meteor storm is coming, and that they won't have the satellite fixed in time? Surely one of the bright people at NASA would have realized this.

  • There are some wonderful websites already up discussing the shower (possible storm)

    See http://www.leonidslive.com for NASA's webcast and frequently updated meteor counts. BTW- there are some great tips on observing at this site, plus a number of star charts and data sheets, should you want to submit your observations.

    Two other sites that I like are http://www.leonidstorm.com and http://www.space.com

    Maybe we'll get lucky this year. Next year it looks like the Moons phase and location is going to really hamper any observations.

  • As I was driving home from work last night, I saw a string of fireballs streaking through the sky in the vicinity of Dulles Airport (I was on RT28 heading towards Sterling, Va). They were larger than any I've ever seen before and lasted for nearly a minute before burning out. It made my night.

  • No, it went into safe mode automatically when
    it lost the last gyroscope. My understanding is that since astronomical observations can't be done with two gyros, there simply wasn't provision made in the software for two-gyro manuevers. So it is incapacitated until the shuttle flight in December (which is itself being squeezed between wiring problems at one end and Y2K compliance concerns at the other).
  • I'm not gonna watch it...

  • I e-mailed them last time & this, and their response was a long-winded "no, bugger off".
  • The weather was not good, so I didn't go to a dark site, however I got to see a fair chunk (perhaps 1/4) of the sky through a hole in clouds from 4 am to 4:15 am NZDT this morning (=Nov 17 15:00 UT). I saw no meteors during this time.
  • Wait, is the math wrong on that? If we are at -5, doesn't that mean that 2am UTC is 5 hours "earlier" for EDT? Which would be 9pm, no?
  • The view is supposed to the best from Israel and Spain.They showed a NASA aircraft getting ready for observation here (Israel).
  • The article says it will happen at 12:30 "local time" without ever explaining what it is. What the fuck do they mean by "local time"??? When is it (EST)???
  • "is supposed to be between 11 PM and 1 AM (EST?)"

    As I read the articles, the peak is expected to be EARLIER than that time, but below the horizon. The point in the sky that these radiate from rises about 11 PM local time, and the moon sets about 1 AM providing better contrast in a darker sky.

    In the sky, the peak is 4:15 UT (GMT)(with lots of hand-waving about +/- as much as 12 hours). In North America, you need to wait till Leo rises, and perhaps till the moon sets, so you can see what's left of a waning show.
  • I live in the Pacific Northwest (U.S.), where clear skies are rare and fleeting at any time of the year. Last winter this area had something like 90 straight days of rain. At the moment, the sky is clear but there's about a 95% chance we'll have clouds by tonight. I would love to see the Leonids, but I have no way to control the weather. Even if I could, the shower is likely to be much weaker on this side of the world than it is in Europe or even the East Coast; like most, I don't have the resources to travel that far just to see a light show. My point: don't tell someone off just because he wants to watch the meteor shower through whatever means possible. A video of it is better than nothing at all.

    (Of course, if the sky is anything close to clear (ie not actually raining), I'll be out in the nearest open and away from lights area hoping for a show!)

  • I just thought I would mention this since we've been having such a strange winter so far. Here in Phoenix Arizona, it's November 17, and we're still hitting 90 degrees outside. I think mother nature is confused or something. I'm still sweating as I walk between classes during the day.

    The Upside to that is, of course, that I don't have to worry about it being cold outside. I don't even need a jacket at night yet!

    The peak IS supposed to be between 9-10pm EST (2am UT), but the shower is unviewable at that time from the US. Because of the position of the radiant (near the constellation Leo), very few meteors can be seen prior to midnight (local time) and the viewing isn't at its best until after 2am, and improves until dawn. The best part of the world for viewing that is the Middle East, Eastern and Northern Europe, and Africa. However, in the past, predictions for this particular shower have been way off base (18 hours late in the case of the 66 shower, and 12 early in case of last year's). If it arrives 3-9 hours late, the eastern US will be one of the best spots. You'll want to start viewing as early as possible (just before midnight), since (if the predictions are right)the most meteors will be falling then. However, there's no telling if this will be an amazing year like the '66 shower (dozens of meteors per second at the peak), or if it will be just a nice shower (50-200 meteors per hour).

  • "Local time" means you can ignore time zones - when it's 12:30am wherever you happen to be will be the best time for you.

  • The fireball was bright not so much because of size as because it was an Earth-grazer. It wasn't like normal Leonid debris where the Earth basically slams into a cloud of tiny pebbles (think of driving through a bunch of no-see-ums); this was something that was travelling roughly in Earth's orbit and slowly grazed along the upper reaches of the atmosphere. It was in the far North, which suggests a slower planetary rotation time, as well.

    Bolides like this don't always break up, either. There was one a year or two ago (in the Southwest?) that was seen by thousands of people during daylight, but the trace it left suggested that it passed through and then left our atmosphere again.

    Space junk is usually travelling pretty fast (90 minute orbit, compared with 24 hrs for the ground just a couple hundred miles below). We know about the big space junk (Cheyenne Mountain keeps close track of it); this doesn't sound much like a satellite orbit to me. It's possible, though.
